Researchers in wireless Micro-sensor networks (M-WSN) have proposed various protocols for energy conservations. Each protocol is aimed to optimize power utilization in wireless sensor networks. The different protocol approaches optimize power consumption either considering their application areas or network topologies. This paper studies various energy-saving protocols for micro sensor networks...

In this paper we are proposing a new concept in MAC layer protocol design for Cognitive radio by combining information held by physical layer and MAC layer with analytical engine based on knowledge based reasoning approach. In the proposed system a cross layer information regarding signal to interference and noise ratio (SINR) and received power are analyzed with help of knowledge based reasoni...

Several transmit power control MAC protocols have been designed primarily to reduce the energy consumption in wireless ad hoc networks. On the other hand, many adaptive rate MAC protocols have been mainly proposed to improve the network throughput. Recently, very few MAC protocols have been suggested by combining the transmit power control and adaptive rate in one algorithm. In this paper, we p...

In our previous work, the limitation of standard type I and II power saving in IEEE 802.16e was discussed, and the idea of load-based power saving (LBPS) was proposed for better power-saving efficiency. LBPS measures traffic load and adaptively generates proper sleep schedule for the current load. Three LBPS schemes have been proposed for mobile subscriber station (MSS) power saving. In this pa...

in this paper, a study and design of energy conservation actions and the obtention of energy efficiency titles, according to the italian ministerial decree 20th july 2004, applied to lighting and electrical systemsin a school district managed by perugia province (italy), is presented.specifically, the analysis regarded the replacement of neon lamps with high efficiency ones, and the power facto...

One of the basic restrictions in Ad Hoc Wireless Networks is energy supply and because of that proposing of power saving protocols that do the normal tasks of network without significantly diminishing the quality of services of the network and consequently, prolonging the lifetime of network has high importance. So, in this paper a distributed power saving technique for multi-hop ad hoc wireles...

Battery energy is a rare resource in MANET and it often affects the communication activities in network. In this paper, we first present an energy management model, in which each node can transfer its state between power-save mode and active mode. Based on such model, we propose a routing protocol for further energy control. In the protocol, a new routing function dealt with both MAC layer and ...

Wireless Sensor Network depends on nodes have limited energy, memory, computational power, range and it is important to increase energy efficiency by saving the battery power so as to extend the life time of the given WSN deployment. In WSN, data is measured by nodes and same is send to Base Station at regular interval. Different protocols are used for energy consumption, in wireless sensor net...
